Too bad you don't give the specifcations, you might get a lot more
interest.

TERRY,

If these Murata 455 Ceramic Filters interest you, then you may
wish to take a look at this replacement for a 455 kHz IF Filter.

"Channel Guard" RX 455 kHz IF Filter.
http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5762938320

* The 455 KHz version is an ultra narrow, 3-pole ceramic filter that
replaces the existing (and broader) 1-pole Murata ceramic filter. (It's
that small black or gray plastic cube soldered into the main CB
chassis.) Just unsolder the old filter, install the 3 CHANNEL GUARD
bare wires into the corresponding empty INPUT/OUTPUT/GROUND holes, and
connect to +8-13 VDC. You are done!

I own a small shirtpocket size Westinghouse AM/FM/Shortwave Radio.About
six years ago,I was listening to it and I laid it down on my couch and I
went to my kitchen.When I got up,it slid off my couch and hit the
hardwood floor.I think it landed on the on/off/volume control knob when
it hit the floor.I removed the chassis from the cabinet and I looked at
it.It looks to me like from the shaft (the knob fits on) on back like a
sort of a little cube shaped affair and quite a few solder connections
where the "cube" was soldered to the radio's circuit board.I know how to
solder but such close quarters as that situation is,I don't think I can
solder it back together properly.I wouldn't mind snail mailing the radio
via UPS to somebody to see if it is worthwhile trying to repair the
radio.Of course,when it hit the floor,it might have damaged something
else too and it might not be worth fooling with.I would be glad to pay
what it's worth to have the radio repaired and shipping and handling
charges both ways.I think it is a nice little radio.Or it used to be
untill it got broken anyway.I know it's around here somewhere if I can
ever find it again.My old house is incredibly full of junk,it's like
some of those horror movies y'all see on tv.The radio is in a bag
because I didn't put the chassis back in the cabinet.

I thought those were CFU-455I................that would be a 4kHz bandwidth
with a 455kHz center frequency. The Z in / out
would be 2k.

Well,now I know what filters look like,as pertains to radios
anyway.(staying on topic here,just like I always do) Nederlands,eh? I
know of a guy in Nederlands (I get his email newsletters,I can prove
that too) who sells genuine World War Two Jeep parts.

I looked up the specs, they are aweful filters

the 40db bandwidth is around 15kHz,,,ouch !!!

the LF-D6 filters I use have a 60db bandwidth of 12kHz.

Don't forget the Murata CFR series! Too bad Murata stopped making them.
Now, about those LF-D6 filters....................I'll take 500,000 of them.
Just kidding!
How is that new MD receiver working out? DR333 or something like that?
